(to send or transport sth. /sb. in a ship) ②形容词转化为动词：green (adj.) → green (v.) (to make ... environmentally friendly) ③介词转化为名词：the ups and downs of life ④连词转化为名词：no ifs, ands, or buts ★派生是指通过给一个单词加前缀或后缀构 成另一个词。（前缀一般改变词义而不改变 词性，后缀一般改变词性而不改变词义）如： 前缀 含义 例子 anti- 反，反对 antisocial 防，防止 antifreeze co- 共同，联合 co-author micro- 微小的 microwave over- 太，过于 overconfident 外面 overcoat 额外 overtime 上方 overhang 后缀 含义 例子 -aholic 嗜好……的， 对……成瘾的 shopaholic, chocaholic -ee 受动者，受益者 employee, trainee -like 类似……的，有……特征的 childlike, shell-like -ed / -d 有……特征的，以……为特征的 talented, bearded, four-legged, blue-eyed -ous 有……性质的 poisonous, mountainous Guess the meanings and parts of speech of the words in italics. 1.
